I think carPC will never die, but most of the DIY carPC community will disappear, as in the
near future, almost all new cars will have an integrated carPC. Like, in 1978, ABS was a luxury,
now, it's standard issue. No phone or home-built pc can compete with a PC designed with
the car itself. You will be able to manage per-user settings for the whole car, like suspension,
seat adjustment, etc, etc. Yes you can do the same with a bazillion of servos, and a DIY pc,
but I will not worth the effort. But, some guys who can't afford the latest Mercedes S-Class
will always try to add the bleeding-edge technology to their twenty year old pickup
Ok, the phones will be stronger, but the PC will always outperform it, and they will not
say: "ok, phones are fast enough for the GPS, disband the developer team, and throw out the plans of our new carPC".
New features will come, and you will need beefier hardware for them.
Navigation in 3D on the HUD, better audio processing, autopilot, and other tasks that we can't even imagine now.
